Bowl of Fruit - General Update Pattern Special Cases
This example demonstrates the general update pattern for data joins in D3, showing how to add, remove, and modify fruit shapes rendered as SVG circles and text labels in a bowl. The code uses `selection.enter()` and `selection.exit()` to handle new and removed data points, while merging entered and updated selections for styling. It relies on `d3.scaleOrdinal` for both color and radius scales, mapping apple and lemon types to distinct visual properties. The animation sequence, driven by `setTimeout`, initially renders five apples, then removes one, replaces another with a lemon, and filters out an additional apple.
